Patent number: 9421338Abstract: A ventilator including a pneumatic system for providing and receiving breathing gas, and a controller operatively coupled with the pneumatic system. The controller is operable to control circulation by the pneumatic system of breathing gas to and from a patient, and to adjust at least one of a volume and pressure of breathing gas delivered to the patient, such adjustment being based upon elastic properties of a component used to fluidly couple the pneumatic system to a patient.Type: GrantFiled: March 12, 2013Date of Patent: August 23, 2016Assignee: Covidien LPInventors: Mehdi M.

Patent number: 9302061Abstract: This disclosure describes systems and methods for detecting and quantifying transmission delays associated with distributed sensing and monitoring functions within a ventilatory system. Specifically, the present methods and systems described herein define an event-based delay detection algorithm for determining transmission delays between distributed signal measurement and processing subsystems and a central platform that receives data from these subsystems. It is important to evaluate and quantify transmission delays because dyssynchrony in data communication may result in the misalignment of visualization and monitoring systems or instability in closed-loop control systems. Generally, embodiments described herein seek to quantify transmission delays by selecting a ventilator-based defining event as a temporal baseline and calculating the delay between the inception of the defining event and the receipt of data regarding the defining event from one or more distributed sensing devices.Type: GrantFiled: February 26, 2010Date of Patent: April 5, 2016Assignee: Covidien LPInventors: Mehdi M.

Patent number: 8905024Abstract: Systems and methods are described for application of a transitory corrective modification to a hot-wire anemometer flow voltage and/or calculated flow rate to compensate for transient thermal response of the anemometer during a change in mixture of a mixed gas being measured. According to one embodiment a method of applying the transitory corrective modification is provided. An output signal of an exhalation flow sensor of a medical ventilator is received. The flow sensor includes a hot-wire anemometer. The output signal is indicative of a rate of flow of expired gas by a patient. Transient thermal response of the hot-wire anemometer is compensated for by applying a corrective modification to the output signal or a value based thereon. The corrective modification is based at least in part on a fraction of inspired oxygen (FiO2) being supplied by the medical ventilator to the patient.Type: GrantFiled: March 12, 2013Date of Patent: December 9, 2014Assignee: Covidien LPInventors: Mehdi M.

Patent number: 8794234Abstract: A ventilator and method of ventilator control. The ventilator includes a pneumatic system for providing and receiving breathing gas, and a controller operatively coupled with the pneumatic system. The controller employs closed-loop control to provide positive breathing assistance to a patient. Supplemental feed-forward compensatory assistance is also provided, in addition to and independently of that commanded by the closed-loop control. The supplemental assistance may be determined, set or selected based on a ventilator parameter and/or an operator parameter, and/or as an automatic ongoing compensatory mechanism responding to varying patient respiratory demand.Type: GrantFiled: September 24, 2009Date of Patent: August 5, 2014Assignee: Covidien LPInventors: Medhi M.
